Hi. Do you press shift p then after a wile 1 or 2? or do you press shift P1/2 thogeter. if you press like the first i sayed its wrong, try shift P1/2 thogeter. if you do that and it still dont work i dont know whats can be the problem. try checking your settings if thats the case. Hope this helps you

If it doesn't help, then you have a very common bug which prevents you from using the "select 1 or 2". If you can normally open more than one door with those keycommands, then you don't have the bug.I have the same bug and what i have heard, so does many other people. Sometimes it works, sometimes it doesn't.
